What This Series Is About
This article is Part 3 of an interactive series that discusses the many
languages that compile and/or run on the Java platform. Java Developer's
Journal invites you to vote for your favorite non-Java programming language
in the JDJ forum. Your vote will decide which languages will be covered by
the series, and in what order. A lot of languages work in the JVM, but this
series will cover only the most popular, as determined by your votes. To
vote: Go to the top of the JDJ Web page and click the forum graphic. Click
the "Enter the JDJ Developer's Forum" link. Go to the Java (Writer's Forum)
section. Click on the link that says "Vote for your Favorite Language that
runs in the JVM." This column is the resting place for non-Java-language,
JVM-related topics for JDJ. It focuses on topics such as: Creating JavaServer
Pages (JSP) in JavaScript, We... (more)
Time is a brutal enemy of youth and exuberance. Time makes cynics of us all.
Time is the universal truth serum that reveals all authenticity. Time will
tell, but the announcement yesterday by Google may change the faces of AJAX
development, strike that, Google's announcement may change web development
for evermore. This cynic heard an announcement yesterday that changed his
viewpoint and beliefs on the future of web development.
Certainly, in the recent past, the chances of doing an entire application in
AJAX seemed remote for the vast sea of developers. The thought of writing a

How can Java classes be used as scriptable components? DCOM, like CORBA,
provides both static and dynamic invocation of objects. DCOM uses type
library to provide metadata to do the dynamic invocation and introspection
similar to CORBA's interface repository or Java's introspection mechanism.
IDispatch, a standard COM interface that supports Automation (late binding),
is great for scripting languages such as Perl, Python, VBScript, JScript and
so on. The Microsoft JVM implements IDispatch automatically for... (more)

If you have not looked into Spring yet, it is time. Here is why you should!
Grady Booch once said that the great thing about objects is that they can be
replaced. The great thing about Spring is it helps you replace them. With
Spring, you simply inject collaborating objects called dependencies using
JavaBeans properties and configuration files. Then it's easy enough to switch
out collaborating objects when you need to. Spring allows you to dynamically
add services to objects called aspects. This is similar to the Decorator
Design pattern, but does n... (more)
Back before Java became popular, I was a C++ bigot. I programmed in nothing
but C++. I lived, ate and breathed C++. If it wasn't C++, it was rubbish. I
thought C++ was the alpha and omega of object-oriented programming. I had
"operator overloading" for breakfast, "templates" for lunch and "multiple
inheritance" for dinner, and I always went back for seconds.
Then a funny thing happened. I got a new job at another company as a C++
programmer. But they pulled the old bait and switch. Once I started working,
someone suggested writing a good portion of a large project in a scripting ... (more)
